Do-It-Yourself Story

After checking the electrical connections (main, heating element, and temperature probe), with an ammeter and the help of a YouTube video of course, the only other possible failure point was the control board. I found it on Appliance Parts Pros and ordered it. The price was great and other customers were very complimentary of their fast shipping speed. Sure enough, the part arrived 2 days later, just as promised. It took about 10 minutes to remove the old control board and install the new one. Very easy - just unplug the connections on the old board and plug them back into the same (easy to identify/remember) spots on the new board. I'd recommend taking a photo of the old board before you disconnect the plugs, just in case. Only a Phillips screwdriver was required. I plugged the oven back in....and.....it works!
